[0002] Surge protector, also called lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other equipment in the circuit. The three-phase surge protector is also a type of surge protector.

[0003] In this regard, China applied for patent number: CN215817519U, which discloses a surge protector, including a surge protector base and a surge protector body. A reserved groove is provided on the surge protector base, and the surge protector body is inserted into the reserved groove. A connecting mechanism is provided on both the upper and lower sides of the interior of the surge protector body. The connecting mechanism includes a rotating part, a clamping part and a pressing part. The rotating part is a long strip structure, one end of which is hinged to the inner wall of the surge protector body, and the other end is a free end. The utility model uses a connecting mechanism to realize the installation of the surge protector base and the surge protector body. The operator only needs to pinch the pressing part by hand to easily pull out the surge protector body. Compared with the traditional technology, the disassembly process of the utility model is more convenient.

[0004] However, in actual use, the surge protector body is troublesome to install and cannot be installed quickly. At the same time, it cannot be limited immediately after installation, and the overall limiting effect is poor. Therefore, it has become an urgent problem to be solved to improve and perfect the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a three-phase surge protector to solve the problem that the surge protector body proposed in the above background technology is troublesome to install and cannot be installed quickly, and cannot be limited immediately after installation, resulting in poor overall limiting effect.

[0006] To achieve the above object, the utility model provides the following technical solution: a three-phase surge protector, comprising a mounting base, a mounting groove is provided inside the mounting base, a three-phase surge protector body is arranged inside the mounting groove, a sliding groove is provided on the top surface of the three-phase surge protector body, and an arc block is arranged inside the sliding groove;

[0007] A telescopic cylinder is installed on the top surface of the inner wall of the mounting base, an arc frame is arranged on the lower surface of the telescopic cylinder, a resisting column is arranged on the lower surface of the arc frame, and a compression spring is arranged on the top surface of the arc frame.

[0008] Preferably, two groups of telescopic cylinders are provided and are respectively installed on the left and right sides of the compression spring.

[0009] Preferably, a back plate is provided on the back of the three-phase surge protector body, and a cooling fan is provided inside the back plate.

[0010] Preferably, mounting bolts are provided inside the back plate, and three groups of mounting bolts are provided.

[0011] Preferably, a stabilizing block is fixedly connected to the left and right sides of the back plate, and an iron block is arranged inside the stabilizing block.

[0012] Preferably, a magnet body is provided on the inner side wall of the mounting base, and the magnet body and the iron block are adapted to each other.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The three-phase surge protector is provided with an installation base, an installation groove, a three-phase surge protector body, a sliding groove, an arc block, a telescopic cylinder, an arc frame, a conflict column, a compression spring, a back plate and a cooling fan. When installing, the three-phase surge protector body is directly installed and pushed into the interior of the installation groove. At this time, the arc frame and the conflict column will conflict with the top surface of the three-phase surge protector body, and the conflict column will slide in the interior of the sliding groove, and the compression spring will begin to be compressed, and the telescopic cylinder will limit the compression spring, so that the conflict column can be fixed in the interior of the sliding groove. When the three-phase surge protector body is subsequently disassembled, the three-phase surge protector body is directly pulled out, and the adaptation between the conflict column and the arc block can prevent the conflict column from being fixed in the interior of the sliding groove, so that the three-phase surge protector body can be disassembled conveniently. The overall operation is relatively simple, and the interior of the three-phase surge protector body can be cooled to a certain extent by the cooling fan. The overall heat dissipation effect is good, which reflects the practicality of the design.

[0015] 2. The three-phase surge protector is provided with mounting bolts, stabilizing blocks, iron blocks and magnet bodies. When the three-phase surge protector body is installed inside the mounting groove, the iron block will be level with the magnet body, so that the magnet body and the iron block are magnetically attracted to each other, so that it is relatively stable after installation. At the same time, the back plate can be installed as a whole to the back of the three-phase surge protector body through the mounting bolts. Therefore, this design can fix the three-phase surge protector body after the three-phase surge protector body is installed, which reflects the functionality of the design.

[0024] The telescopic cylinder 6 is installed on the top surface of the inner wall of the mounting base 1. The lower surface of the telescopic cylinder 6 is provided with an arc frame 7. The lower surface of the arc frame 7 is provided with a conflict column 8. The top surface of the arc frame 7 is provided with a compression spring 9. The telescopic cylinder 6 is provided with two groups, which are respectively installed on the left and right sides of the compression spring 9. When installing, the three-phase surge protector body 3 is directly installed and pushed into the inside of the mounting groove 2. At this time, the arc frame 7 and the conflict column 8 will conflict with the top surface of the three-phase surge protector body 3, and the conflict column 8 will slide in the inside of the sliding groove 4, and the compression spring 9 will be compressed. 9 starts to be compressed, and at the same time, the telescopic cylinder 6 limits the compression spring 9, so that the abutment column 8 can be fixed inside the sliding groove 4. At the same time, when the three-phase surge protector body 3 is subsequently disassembled, the three-phase surge protector body 3 is directly pulled out.

At the same time, the compression spring 9 begins to compress, and the telescopic cylinder 6 limits the compression spring 9, so that the abutment column 8 can be fixed inside the sliding slot 4. At the same time, when the three-phase surge protector body 3 is disassembled later, the three-phase surge protector body 3 is directly pulled out, and the adaptation between the abutment column 8 and the arc block 5 can make the abutment column 8 It will not be stuck inside the sliding groove 4, so it is convenient to disassemble the three-phase surge protector body 3. The cooling fan 11 can dissipate the heat inside the three-phase surge protector body 3. When the three-phase surge protector body 3 is installed inside the installation groove 2, the iron block 14 will be horizontal with the magnet body 15, so that the magnet body 15 and the iron block 14 are magnetically attracted to each other, so that it is relatively stable after installation. At the same time, the back plate 10 can be installed as a whole on the back side of the three-phase surge protector body 3 through the installation bolts 12. Therefore, this design can fix the three-phase surge protector body 3 after the three-phase surge protector body 3 is installed. The above is all the working principles of the utility model.

[0026] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
